Recommended todo list application

Thought I'd break my first post with a request for recommendations on a decent todo list application. Preferably something that includes reminders, categories, or something that resides in the menu bar. Any ideas?

In Leopard to-do lists are becoming a system wide feature that I believe is open for other devs to use in their apps. You might wanna wait unless it's freeware. I could be remembering wrong though, I know it's at least added to mail.app and integrates with iCal. I'm really hoping for some iCal and gCal syncing myself. I heard that the Spanning Sync thing might end up being a subscription service. Boooo!

Oh, and High Priority. If you use To Do Lists in iCal, YOU NEED High Priority. If you wished you could use To Do Lists in iCal, you need high priority. If you like to keep track of tasks, you need High Priority.

I've never really done to do lists but after checking out how easy it is with high priority I think I'm gonna start. I'll at least try it out and see if I like it. Thanks man!

I'm a supporter of the Kinkless GTD system, but the developer has since ceased upgrading and has joined forces with Omni to make the recently released Omniplan beta. This program runs David Allen's GTD to a degree (I'm still poking around in it and I'm not totally sure how orthodox it is) and has benefited from Merlin Mann's (of 43folders.com) input. The nicest thing I've noticed at first glance is a visualization window for projects which shows what tasks are depending on what other tasks or resources.

@epochblue - don't mention it! I was surprised the author hadn't posted this to VT or MU; he's also good with updates, fixing one major issue with adding entries pretty quickly.

I've been using GTD myself lately - I use an installed combination of Tracks and Locomotive. It's more clunky than things like Frictionless, Actiontastic, Omniplan or the lamented iGTD, but the nice thing about it is that I can install it on both my Windows box in the lab and on my own machine and sync my GTD items between them.
